FAN ATTACHMENT FOR ROCKING-CHAIRS.

To all whom it may concern Be it known that I, ALOIBIADE A. Buo- DEUR, a citizen of the United States, reslding at WVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Fan Attachment for Rocking-Chairs, of which the followlng is a specification.

This invention relates to a fan attachment for rocking chairs of the pendulum type.

The principal objects of the invention are to provide an improved means for mounting the pendulum and for connecting it with the fan, and to simplify the construction so that it can be made with comparative oheapness and yet retain the maximum EH'lClBllCY of this type of fan attachment.

The invention also involves improvements in details of construction as will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Figure 1 is a side view of a part of a rocking chair showing a preferred embodiment of this invention applied thereto and illustrated largely in section; Fig. 2 is an end view of the same; Fig. 3 is a side view of the attachment; and Fig. 1 is a sectional view vertically through the center of Fig. 3 on enlarged scale.

The invention is shown as comprising a single hollow semi-circular casing 10 constituting the frame of the device. This is pro, vided with front and back plates separated from each other and integrally mounted on the front plate is a transverse plate 12 flat on the bottom, below which is a lug 13 for the binding screw 14:. It is by these parts that the device is secured to the arm of the rocker.

The plate 12 is provided with a partially cylindrical boss 15 thereon which is traversed by a central passage. In this passage is a shaft 17 and the end of the passage is closed by a screw 18. This shaft has a bearing in the passage and it projects across the casing into a second bearing in the opposite plate. On this shaft is fixed by means of screws 19 a casting 20 from which depends a long arm 21 for supporting the weight or pendulum 22. The upper part of this casting is provided with a curved rack 23 having its teeth on one side.

A projection 25 extends up from the top of the casing. This projection is hollow Specification of Letters Patent.

and through it extends the fan shaft 26. This is provided with a collar 27 for holding it in proper position on the projection 25 and at the bottom it has a bevel pinion 28 meshing with the rack 23. At the top it is provided with an adjustable holder 29 for the fan so that the fan can be placed at any desired angle.

In setting up the parts the fan shaft is passed up through the projection 25 and the collar 27 and holder29 attached. Thus the casting 20 is placed within the casing, so that the rack comes into mesh with the pinion. Then the shaft 17 is introduced through the central passage 16 until it passes through a perforation in the casting into the opposite hearing. The screws 19 are tightened up to secure the casting to its shaft and the screw 18 is inserted into the passage 16 in proper position longitudinally. All that is necessary to do now is to apply the device to the rocker arm and tighten up the screw 14:.

With every rocking motion, no matter whether it is a short one or a long one, the pendulum will swing, causing the fan to operate even when the rocking motion is very slight. In addition to this, after the rocking ceases the pendulum will continue to swing for some time as the friction of the parts is very slight. The mounting of the parts in the casing is a feature of the invention and is designed to reduce the friction and also to simplify the parts and reduce their number.

Although I have illustrated and described a preferred embodiment of the invention, I am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore I do not wish to be limited to all the details of construction herein shown and described, but i What I do claim is In a fan attachment for rocking chairs, the combination of a semi-circular hollow casing having an integral hollow projection extending up therefrom, a shaft mounted to rotate in said hollow projection and extendingdown into the casing, a pinion on the end of said shaft in the casing, a plate extending outwardly from the casing below the center thereof and having a base there on provided with a longitudinal passage therethrough into the casing, a shaft in said my hand, in the passage projecting across 1the casing an?
